Select a video codec with which to encode your content from the Video codec pop-up menu. If you are authoring for Flash Player 6 or 7, choose the Sorenson Spark codec; if you are authoring for Flash Player 8, choose the On2 VP6 codec. 3. Select a frame rate. By default, Flash Video Encoder uses the same frame rate as the source video. Macromedia recommends using the default frame rate unless you are very experienced with video encoding, and have a specific application that requires modifying the source video's frame rate. If you need to alter the frame rate, be sure you understand how modifying the frame rate affects the video quality. If you intend to embed video clips within the SWF file, the frame rate of the video clip must be the same as that used by the SWF. Using the Advanced Video Encoding settings in the Video Import wizard, you can encode video using the same frame rate as the FLA file. For more information, see "About embedding video in a SWF file" on page 276. N OT E For more information, see "About encoding video" on page 281. 294 Working with Video 4. Select the keyframe placement for the video. Keyframes are video frames that contain complete data. For example, if you specify a keyframe interval of 30, Flash Video Encoder encodes a complete frame every 30 frames in the video clip. For frames between keyframe intervals, Flash stores only the data that changes from the preceding frame. By default, Flash Video Encoder places a keyframe every two seconds of playback time. For example, if the video you're encoding has a frame rate of 30 fps, a keyframe will be inserted every 60 frames. In general, the default keyframe value provides a reasonable level of control when seeking within a video clip. If you need to select a custom keyframe placement value, be aware that the smaller the keyframe interval, the larger the file size. 5. Specify the quality of the video from the Quality pop-up menu. The quality setting determines the data rate (or bit rate) of the encoded video. The higher the data rate, the better the quality of the encoded video clip. To specify a quality setting, do one of the following: Select a preset quality setting (Low, Medium, or High) to automatically select a Data Rate value. When you select Low, Medium, and High from this menu, the Maximum Data Rate text box updates to reflect the specified value. Select Custom and enter a value, in Kilobits/Sec, in the Maximum Data Rate text box. If you find that the preset quality settings are not working with your particular source footage, try specifying a custom maximum data rate. For more information on data rate and how it affects video quality, see "About encoding video" on page 281. N OT E 6. To resize the video clip, do the following: a.
